Jacques le Berre, director of market and business development for NXP's semiconductor lighting products, said: "The energy efficiency of LED lighting is expected to reach 10 times that of incandescent lamps. According to the manufacturer's report, LED lamps can last for more than 50,000 hours. Key electronic components, especially The reliability of LED driver ICs is critical to the overall reliability of LED lighting products. We have been conducting accelerated life testing for more than 7,000 hours, and this result will be more optimistic as the test progresses. , has established a new benchmark in the industry, and proves that NXP's LED-based driver ICs have the ability to support ultra-long-life lighting fixtures. In addition, our latest SSL2102 products and online design tools can help innovative lighting companies. accelerate the pace of product development and accelerate the adoption of LED lighting fixtures in the general lighting market.

LED driver IC life test
NXP is conducting the industry's longest running LED driver IC accelerated life test, which began in December 2008 with zero fault operation. As of now, the test has been running for 7,000 hours and continues, proving that NXP's LED-based driver ICs based on utility power fully meet the long-life requirements of LED products. Traditional life testing procedures in the semiconductor industry are typically based on 1,000 hours of testing time, and NXP's testing goes far beyond this standard.
NXP's ongoing accelerated life testing is aimed at the industry's first integrated dimmable commercial LED driver IC product, the SSL2101, released earlier this year. NXP randomly selected a batch of SSL2101 IC drivers from standard production products to test under high stress conditions. All test samples maintained full functionality after running for more than 7,000 hours at an IC junction temperature of 150 °C. NXP has adopted multiple tests and different settings to detect all possible failure modes in several use cases, including continuous on, on/off switching cycles, and various combinations of uses. Based on the lifetime acceleration model, the estimated lifetime of SSL2101 in real lighting applications is estimated as follows:
Lifetime exceeds 60,000 hours at 105 °C
Lifetime exceeds 35,000 hours at 115 °C
Life expectancy exceeds 20,000 hours at 125 ° C
Lifetime of more than 7,000 hours at 150°C As part of Enzhi NXP's evaluation of the actual life of its latest LED driver IC, the test uses a continuous operation reliability method that continues until the end of product life.
The latest LED integrated commercial power dimming driver IC supports 25W maximum power
The SSL2102 is the latest addition to NXP's lighting portfolio, with deep dimming capabilities down to 1% of full light intensity and compatibility with a wide range of dimmers. This small size, highly integrated, high efficiency LED driver IC is a compact LED lighting breakthroughs, is ideal for small sealed enclosure with LED lighting applications.
The SSL2102 is suitable for energy efficient and high power factor LED lighting applications, including: 8W to 15W compact applications; 15W to 25W LED modules for applications such as LED spotlights and downlights; and mall counters with a maximum power of 25W Use LED light string .
The main features of SSL2102 include:
Visual natural dimming with built-in logarithmic dimming curve
Supports most dimmers on the market (eg thyristor, transistor type)
High integration, few external components required
Switching power supply design with isolated and non-isolated architecture
SO20 wide body package with enhanced heat dissipation
Best energy efficiency valley switch detection
Built-in demagnetization detection
Built-in overheat protection (OTP)
Supports the LED driver IC from the rectified mains voltage as an integrated dimming controller and switching power supply module. The SSL2102 has the same function as the SSL2101, but with higher power support, enabling design customers to apply a design to the power rating range. A wide variety of different end products.
SSL application online design tool
NXP's latest SSL application online design tool allows engineers to easily and easily measure NXP's LED driver ICs. NXP's line has four products, each of which is a new product for dimmable products. SSL2102 and SSL2101, as well as SSL1522 and SSL1523 for non-dimmable products.
